Sec. 4-22-010. Purpose. ¶
This Chapter lists the land uses that may be allowed within the residential zoning districts, determines the type of planning permit/approval required for each use, and provides basic standards for site layout and building size.
Sec. 4-22-020. Definitions of the residential zoning districts. ¶
The definitions of each residential zoning district and the manner in which they are applied are as follows:
A. R-E (Residential Estate) zoning district. The R-E district is applied to areas appropriate for large-lot, single-family residential development, together with limited agricultural uses. The maximum allowable density is two dwelling units per acre. The R-E zoning district is consistent with and implements the Residential Estate District land use designation of the General Plan.
B. R-1 (Single-Family Residential) zoning district. The R-1 zoning district is applied to areas appropriate for neighborhoods of detached single-family homes, and related, compatible uses. The maximum allowable density is 2 - 7 dwelling units per acre. The R-1 zoning district is consistent with and implements the Low Density Residential land use designation of the General Plan.
C. R-2 (Medium Density Residential) zoning district. The R-2 zoning district is applied to areas appropriate for neighborhoods with a mixture of housing types, including detached single-family homes, zero lot line homes, duplexes, and related, compatible uses. The maximum allowable density is 10 dwelling units per acre. The R-2 zoning district is consistent with and implements the Medium Density Residential land use designation of the General Plan.
D. R-3 (Multiple Residential Medium/High Density) district. The R-3 zoning district is applied to areas appropriate for a variety of housing types, including small-lot singlefamily housing, and various types of multi-family housing (for example, duplexes, triplexes, and townhouses). The maximum allowable density is 20 dwelling units per acre. The R-3 zoning district is consistent with and implements the Residential - Medium/High Density land use designation of the General Plan.
E. R-4 (Multiple Residential High Density) district. The R-4 zoning district is applied to areas appropriate for a variety of higher-density housing types, including small-lot single-family housing, and various types of multi-family housing (for example, triplexes, quadplexes, townhouses, and apartments). The minimum allowable density is 20 dwelling units per acre and the maximum allowable density is 25 dwelling units per acre. The R-4 zoning district is consistent with and implements the Residential - Medium/High Density land use designation of the General Plan.

ARTICLE 2 ALLOWABLE LAND USES AND ZONING DISTRICT STANDARDS CHAPTER 4-22. RESIDENTIAL ZONING DISTRICTS Sec. 4-22-020. Definitions of the residential zoning districts.
- F. P-D (Planned Development) district. The P-D zoning district is applied to greenfield areas within the City that are intended for the development of new neighborhoods. As noted by the General Plan, "This use combines residential development densities to allow for a broad range of housing options, while trying to eliminate "cookie-cutter" housing. The P-D zoning district is also intended to provide for new neighborhoods that are based upon traditional neighborhood development (TND) design features. The P-D zoning district is consistent with and implements the Planned Development land use designation of the General Plan. Allowable density is 1 to 6 units per gross acre.
